Makes me wish I would have read more on FT before booking my flight as my schedule was flexible and the price was similar for CO 84/85, but I ended up taking the CO 90/91 not knowing better. I guess I'll know for next time.
This brings up a separate question on whether there's a site or list somewhere which compares or identifies the better flights between two locations. ie: given 2 to 8 flights between EWR and another destination, whats the difference in service, on time arrival, etc.
